<P>PROBLEM TO BE SOLVED: To suppress a frequency of a double paper feed event, thereby improving working performance of a user. <P>SOLUTION: This paper feeding apparatus including, as a double paper feed prevention mechanism, a conveyance roller rotating forward in a paper feeding direction and a handling roller rotating rearward in an opposite direction to the paper feeding direction through a torque limiter and being driven by the conveyance roller when the number of fed sheets of paper is one includes a double paper feed detection sensor disposed at a downstream side of the double paper feed prevention mechanism to detect a physical quantity corresponding to the number of fed sheets of paper, and a control unit that determines a frequency of double paper feed events at the downstream side of the double paper feed prevention mechanism in the unit of a job based on an output signal of the double paper feed detection sensor, lowers a rearward rotation speed of the handling roller when the frequency of double paper feed events is equal to or more than a first threshold and recovers the rearward rotation speed after the completion of the current job. <P>COPYRIGHT: (C)2013,JPO&INPIT |
